Problems solved by technology

This combination makes MBSFN transmission different from unicast transmission, and makes the performance of MBSFN transmission difficult to be verified than unicast transmission.
There is no feedback to the radio access network (RAN) which broadcasts the MBMS transmission, such as hybrid automatic repeat request (HARQ) or radio link control (RLC) acknowledgements, meaning that the RAN does not know whether the MBSFN transmissions are successfully received or not.
Hence, ...

Embodiment Construction

[0021]It is desirable to have automated solutions, to provide the ability for network operators to gather information such as radio measurements which are associated with customer UEs and use this information to assist network operation and optimization.

[0022]Please refer to FIG. 1, which is a schematic diagram of a wireless communication system 10 according to an embodiment of the present invention. The wireless communication system 10 is briefly composed of a network and a plurality of user equipments (UEs). In FIG. 1, the network and the UEs are simply utilized for illustrating the structure of the wireless communication system 10. Practically, the network may be a universal terrestrial radio access network (UTRAN) comprising a plurality of Node-Bs (NBs) in a universal mobile telecommunications system (UMTS). Alternatively, the network may be an evolved UTRAN (E-UTRAN) comprising a plurality of evolved NBs (eNBs) and / or relays in a long term evolution (LTE) system, a LTE-Advanced...

Abstract

A method of handling a multimedia broadcast multicast service (MBMS) minimization of driver test (MDT) for a network of a wireless communication system includes transmitting a first MBMS measurement configuration to instruct a first user equipment (UE) to perform an MBMS MDT operation; receiving a first MBMS measurement result and a first multicast-broadcast single frequency network (MBSFN) area identity (ID) which indicates that the first MBMS measurement result is generated for a first MBSFN area identified by the first MBSFN area ID, from the first UE; and processing the first MBMS measurement result according to the first MBSFN area ID.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 926,972, filed on Jan. 14, 2014 and entitled “Method and Apparatus for handling MBMS MDT logging in a wireless communication system”, the contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a method utilized in a wireless communication system, and more particularly, to a method for handling a multimedia broadcast multicast service (MBMS) minimization of driver test (MDT) in a wireless communication system.[0004]2. Description of the Prior Art[0005]A long-term evolution (LTE) system supporting the 3rd Generation Partnership Project (3GPP) Rel-8 standard and / or the 3GPP Rel-9 standard is developed by the 3GPP as a successor of a universal mobile telecommunication system (UMTS) for further enhancing performance of the UMTS to satisfy increasing needs of users. The LTE s...
